Answer:
the answer is number 4......
I think it would be .08, as 100 is equal to 10^2.
On a phone here and no access to paper but you must first find the midpoint of AC which is the average of the coordinates. The perpendicular bisector will have a gradient that multiplies by AC's gradient to make -1. This will obviously pass through its mid point so as long as you know how to use y=mx+c you should be good.
Your answer choice would be B.
Y is your quantity
You minus 12 so...
Y - 12
Then it's two times that so...
2(Y-12)
